Lisp function to convert string to list9/10/2023 ![]() ![]() It takes a string character(s) as first argument and a string as the second argument and returns a substring where all characters that are in the first argument are removed off the end of the argument string. It takes a string of character(s) as first argument and a string as the second argument and returns a substring where all characters that are in the first argument are removed off the beginning of the argument string. It takes a string of character(s) as first argument and a string as the second argument and returns a substring where all characters that are in the first argument are removed off the argument string. The following table describes the string trimming functions − Sr.No. (write-line (string-capitalize "a big hello from tutorials point")) (write-line (string-upcase "a big hello from tutorials point")) The following table describes the case controlling functions − Sr.No. (write (string-not-equal "this is test" "This is test")) (write (string/= "this is test" "this is Test")) (write (string-lessp "this is test" "This is test")) (write (string-greaterp "this is test" "This is test")) (write (string-equal "this is test" "This is test")) (write (string< "this is test" "This is test")) (write (string> "this is test" "This is test")) (write (string= "this is test" "This is test")) The following table provides the functions − Case Sensitive FunctionsĬhecks if the values of the operands are all equal or not, if yes then condition becomes true.Ĭhecks if the values of the operands are all different or not, if values are not equal then condition becomes true.Ĭhecks if the values of the operands are monotonically increasing.Ĭhecks if the value of any left operand is less than or equal to the value of its right operand, if yes then condition becomes true.Ĭreate a new source code file named main.lisp and type the following code in it. One set is case-sensitive and the other case-insensitive. ![]() ![]() Common LISP provides other two sets of functions for comparing strings in your code. Numeric comparison functions and operators, like, do not work on strings. When you execute the code, it returns the following result − (write-line "Welcome to \"Tutorials Point\"") Exactly how to do this will not be covered here as it makes a nice exercise to develop your understanding of LISP input processing.(write-line "Welcome to Tutorials Point") ![]() It is then possible to inspect each character and process it appropriately if it is problematic. If punctuation is likely to appear in input, then it is necessary to use read-char, which reads one character at a time. >(string-to-list "Commas cause problems, see")Įrror: A comma has appeared out of a backquote. >(string-to-list "this is a string of text")īecause of its reliance on read, this function will not work with certain kinds of punctuation. (do* ((stringstream (make-string-input-stream str)) Here is an example of code to convert a string to a list: If the objective is to parse the input, it is much more convenient to have a list of words than a string. For example, to get substantial input, read-line is most convenient, but it returns a string. Sometimes it is useful to convert text strings to lists.
